I just set up a system with three displays, and I just ran into this issue. However, for me, the issue is that one of my two identical monitors (2 x Eizo EV2336) are getting REC 709 over DisplayPort. I have two separate computers using these three monitors in different ways, and the custom resolution "fix" doesn't work with cloned displays, so it isn't a fix at all, for me, really.
This whole thing make me wonder if nVIDIA have gone completely bonkers. Feeding REC 709 to computer displays? Absolute madness.
I work in the TV business, and I've done my share of setting up monitoring systems and editing suites, and never in my life would I have thought anyone could be quite so deranged as to force a specific esoteric (to the PC platform) colour space onto equipment by default, and not even include any settings for it.
The EDID argument simply doesn't work because nVIDIA knows that they can't trust EDID, and that an option to manually force colour space is therefore needed. The argument that HDMI is mostly used for TVs, so one shouldn't complain, is absolutely ludicrous. HDMI can be used for all sorts of things, and transporting identical data streams to DVI data streams is one of them. nVIDIA is not to decide what people use HDMI for. If I want to use it for a computer monitor, I will.
In my case, it's happening with DisplayPort, which is standard on pretty much any display right now, regardless of what kind of colour space it is made for. It makes me livid that there are people at nVIDIA wilfully ignoring this issue at this very moment, when thousands upon thousands of customers are affected.
nVIDIA needs to fix this right now, as the state of things at the moment is completely unacceptable. Their graphics cards are outputting erroneous data, and it's not even a bug, all of them are doing it as a rule, because nVIDIA makes them do it.
